gcc，clang，msvc等编译器有什么区别？第1页

mai-wen-xue-67 网友的相关建议:

俺的了解十分肤浅。俺没啥文化，初中毕业，大伙都知道。

但是 GCC 给俺的记忆十分深刻，就是错误或者警告提示可以有彩色的。

VS CODE 不装插件怎么搞彩色的警告错误提示 COLORFUL WARNING

老实说，俺也是在自己的另一台电脑上注意到有这个玩法。

还花了一个晚上阅读 VS CODE 的说明。

时间就是这样浪费掉的。

但是，没找到任何有用的提示。

今天终于在寻找 GCC 的编译开关时发现了这个诀窍。

分享给大家。

"-fdiagnostics-color=always"

       -fdiagnostics-color=always   俺菜鸟， 所以也用上这个                 "-Wall",                 "-Wextra",

当然，很可能许多人知道，但俺是第一次了解。

       "-fdiagnostics-color=always"    俺菜鸟， 所以也用上这个                 "-Wall",                 "-Wextra",
